I hope this is the right place.  I have been having the most awful time trying to get a character right.  I got a few snippets of how I want him to be and what he does, but I can't - for the life of me - figure out how to put it together in one cohesive story.  So I'll start from scratch, and I'd ask that some of you please help me.

It's a western, taking place in the American Frontier sometime in the late 1800's.  The apparent [i]theme[/i] of the story is revenge - but that's not what its about.  Two unlikely individuals, John Taylors (an experienced outlaw, bounty hunter, and drifter) and Lillie Williams (a young, naive, 12 year old girl) embark on a quest to track down and either kill or capture a notorious outlaw by the name of Butcher Bill.  The story would be about the father-daughter bond that grows between the two characters.

Now there's a lot of different routes to go with this but here's a few key events I want happening:
1.  Both characters have been hurt by Bill.  This is one of the prime reasons John is helping Lillie.
2.  Maybe John's wife and daughter was killed by Bill, turning him into a shell of his former self.  But Lillie reminds John of his daughter and this helps to build that father-daughter relationship I want.  What do you make of that?
3.  Perhaps John and Bill knew each other beforehand.  Are they brothers, perhaps?  Did they ride in the same gang?  This would make it more personal for John and I like that.
4.  I want several years to have passed by (maybe 3?) since John's family has been killed.  But what reason would John have for not seeking Bill before this story?  Do you think it's realistic that Bill had been hard to find and John has just been roaming around the west waiting to hear something about him?
5.1  This idea sees Lillie survive an attack by Bill.  She comes into town, her story sparks interest by John.  John is the only one willing to go after Bill, and Lillie tags along, but only because she knows where Bill is hiding out at.
5.2  This idea sees Lillie being captured and will be ransomed off the sheriff.  Instead, the sheriff forms a posse and John joins in.  John is about to kill Bill but he holds Lillie at gunpoint.  Bill manages to flee, and this is when John and Lillie team up to track him down.
6.  I had considered that they run across Cassius Green, Bill's right-hand man.  Lillie wants him to die, because he helped kill Lillie's family, but John doesn't want to kill him... but for what reason?  This would cause some dynamic between the two characters.

So with this information, construct some sort of background or bare-bones summary that you think works.  Feel free to add onto things or take things out if you want.
